With a double flange suitable for use in standard in-line cavity wall details, these cavity closers can also be used in sill details by easily cutting a length to fit the width of the window and positioned in the cavity at the sill. In horizontal applications, a damp-proof course (DPC) is still recommended.
These lightweight closers are suited to fit a 125mm cavity width. With a straightforward installation process free of special tools, the lengths can be simply cut with a saw without impacting the thermal efficiency. For some specific products, PVC flanges offer a secure method of fixing.
These cavity closers from Manthorpe are ideal for use around timber windows and doors. When tested as a whole detail, including plasterboard and timber door/window frames, they can be used as a part of a detail to comply with the requirements of a cavity barrier as defined in Part B of the building regulations.
The closers are available in individual lengths, or some might be fixed directly onto door and window frames or pre-formed into frames. G245 and G246 Plastic Fixing Clips allow the closers to be mortared securely to the brickwork and enable the joining of shorter lengths to minimise wastage.
